[SOLVED] Ryzen 5 3600 High idle temperature

[xerocry]

Hi,
I have Ryzen 5 3600 with cooler Scythe Mugen 5 Rev.B . I have high idle temps 50-60c with just Chrome with 10 tabs and when i start running some software or games it goes to 75c. Why?
I installed 2 intake coolers(2x Arctic P12 PWM PST ) and 1 exhaust Noctua NF-A12x25 PWM displayed on pic 1. Case in Fractal Define C. I think I applied thermal compound correctly(?). Windows 10 is on balanced plan.
Maybe fan config is wrong? Or such temps are normal for that CPU at those fans speeds?

I have the same cooler on 3800X and my idle temps are way lower so check your cooler install again.

Pretty sure I installed it correctly. Could too much thermal compound be an issue? Should I apply only a drop instead of making a layer?

What kind of temps are you seeing when stressing it, like on Cinebench? The 3600's can run pretty warm, even at idle but if it's only hitting 75 degrees when gaming, i'd say that's pretty normal, if not, not bad at all.

Google chrome with 10 tabs is hardly what i would call an idle state. Chrome tends to use a lot of resources, depending if those tabs are running anything it will just exacerbate the situation. What are your temperatures when chrome is completely shut down? 75C is really not that bad for a gaming load. Can you run userbenchmark?

Sure,

CPU: AMD Ryzen 5 3600 - 77.1%
GPU: Nvidia RTX 2070S (Super) - 124.9%

HDD: WD Blue 1TB (2012) - 89.5%

You need to enable XMP in the BIOS as your RAM is only running at 2667mhz and not 3200mhz.

. During multicore cinebench test temp goes to 82-83c..

I heard that XMP is bad and only for overclocking, is it safe to turn it on?

Have you tried running it with the side off the case? if the idle temp under the same load is much lower you have an air-flow problem, and if not, I would try re-applying the thermal compound, you could have a bubble or something, it happens sometimes

btw. correct application of thermal compound can become a huge debate, but I have learned that most methods seem to work fine

Hm, without front part of case and XMP enabled - I've got 72-76c during multicore Cinebench..
Will also try to reapply compound.

Don't know what to do with front part, it only has holes on sides, so what's the right way to do airflow with it? 2 exhaust fans with 1 intake? Put another intake on the top part?

Depends on what is in tabs...
With my Chrome 20 tabs i have 40 degrees "idle"
5600x

As gamers nexus has shown to the ire of builders, unless your thermal compound is conductive, you cannot, within reason, apply too much thermal compound. Generally you want enough compound to completely cover the top of the CPU IHS. Too little can be an issue. Just to be sure, some coolers come with a plastic film where it contacts the CPU IHS, if you failed to remove this before you installed it on the CPU thermal performance will greatly suffer as plastic film is a thermal insulator, not a conductor.

it looks like you have 10c difference with and without the front cover, that's actually not too bad, I've been handed PC's for attempts at up-grades by friends where the air flow is so bad that taking the cover off the case makes 35c difference to the temps, there's still room for improvement tho

any chance you can upload an actual photo of your PC?

I guess there is only room for three fans on the case? giving rise to the positive vs negative pressure argument, I personaly always go with positive pressure (2 incoming and one outgoing), partly because the PSU has a fan that also removes air from the case (acting as your 2nd outgoing), and partly because positive pressure pushes air out of all the other gaps in the case, resulting in more air flow overall, but other people will likely say different

[EDIT] what I say above only makes sense if the case has room for 2 incoming fans mounted on the inside of the front cover, the fans on the top and back should always be outgoing because heat rises

you could also get fans with a higher airflow rate than the ones you already have, but be warned, unless they are noctua, they will probably be noisy

Just to be sure, some coolers come with a plastic film where it contacts the CPU IHS

Ahhh the problems people have when they can afford new stuff, I have never has a CPU that isn't second hand 😳

Why CPU... it is cooler stuff.
New coolers can have sticker on bottom plate to protect it from scratches.

you see, I wouldn't know, I've never had a new cooler 😛

Well i may go similar road for GPU at some point... never bought used stuff before.

I think your method is fine I do the same and spread it to get coverage. More check if it is tight. In all reality your load temps are fine so wonder what the temps are with nothing running except windows?

Thanks for the help a lot!

PC: Front look and Side look. I assume yes, I only have place for 1 fan in front because of long video card. 2 Arctics are working as intake, Noctua as exhaust.
Also, could it be that fan settings are bad and like my case needs more RPM for them constantly?

Jesus that GPU size alone...
Dangm they are so expensive in my country, that i cannot afford to buy even used one atm... Need to collect much more money

Basically same as with Chrome, maybe a couple degrees less. 83c with front cover is okay, right?

Haha, yeah, I bought a compact case before I bought 2070 super(just before GPU crysis), and I still just don't want to change case cause most of them are so big and ugly. 'Define C' is compact, minimalistic and nice, without that CRAZY RGB and other "pro-gamer" stuff

Actually not ok, unless it is 4 thread Prime95...
If it is just Chrome, i may have bad news.

83c under benchmark load, not in idle. I remember it being nearly the same in Horizon: Zero Dawn.

Well benchmarks are also difference
Like my CB23 temp is up to 77 degrees with my air cooler.
While 4 thread Prime95 Small FFT gives me up to 80.5 degrees
And i have mine OCed, but also UVed...
So... 83 with a average bench is... really not very nice, if you also have no PBO limit enchanced.
With stock limits i will barely hit 65 degrees, because it is only 76W. My limit instead is 91W, that's why temps are like these

Cooler requires good pressure and decent mount. I managed to pull temps down 2-4 degrees JUST BY MOVING COOLER PLATE!!! Just by aligning copper tubes against chip placements allowed me to do it. So you cannot just throw away cooler as one of possible reasons

Maybe your thermal compound is really strange and pressure not enough. So on cold boot you get almost no cooler contact, until paste heats up and spreads. But it happens too late.
Maybe reason is in something else, idk

Side look.

Ok, what's the fan on the cpu cooler doing? Is it facing the same direction as the front and rear chassis fans?
That top fan also doesn't add up.

Seems you're right. Just aligned CPU cooler with front and back, make CPU screw tight. Also moved and reversed top one.
But no big changes, ~45-55 idle on PC start, 77-80c with CB23.
